ATSDR assessed the exposures using ATSDR's public health assessment evaluation process and reviewed available scientific literature regarding the effect of chemical interactions on the overall potential adverse health effects of contaminant
and hormonal profiles have been reconstructed for an individual male blue whale (Balaenoptera musculus, Linnaeus 1758) using the earplug as a natural aging matrix that is also capable of archiving and preserving lipophilic compounds.
Increasing the ventilation rate led to lower contaminant
concentrations but not necessarily higher ventilation effectiveness.

The ground water located beneath the United Nuclear Corporation Superfund Site is mostly contaminated by what EPA officials say are secondary drinking water contaminants
. In other words, these contaminants
are aluminum, chloride, manganese, sulfate, and dissolved solids, which are solids that can filter through two-micrometer pores.
Given the number of chemicals in the environment and people's variability in exposure and susceptibility to harm, it's a daunting challenge to catalog all possible drinking water contaminants
and assess their associated health risks.
may end up in surface and ground waters, and minimizing such damage is important to feedlot operators.
Anything that disperses the contaminant
or causes it to adsorb on pigment will prevent or reduce cratering.
According to the Safe Drinking Water Act, the EPA established the Unregulated Contaminant
Monitoring programme, to identify contaminants
that are suspected to occur in public water systems and which may warrant regulation.
As the Environmental Protection Agency weighs whether to define coal ash as hazardous waste, a study published in Environmental Science and Technology identifies new monitoring protocols and insights that can help investigators more accurately measure and predict the ecological impacts of contaminants
The problem becomes noticeable when the contaminant
level rises to the level of the pick-up tube.
Mazumdar (2009) found that a moving passenger in an aircraft cabin could carry a contaminant
in his or her wake to positions far from the contaminant
More than 20% percent of untreated water samples from 932 public wells across the nation contained ar least one contaminant
at a concentration of potential health concern, according to a study by the U.S.
Perchlorate is another example of an emerging contaminant
. Perchlorate salts are used widely in explosives, solid rocket fuel, matches, and air bags.
Another technique is to use dedicated exhaust ventilation systems to isolate and remove contaminants
by maintaining negative pressure in the area around the contaminant
